In stark contrast to the invasive mouthpiece device developed in the 1980s, known as the breathalyzer, SOBR's 21st Century pre-ignition vehicular device measures actual ethanol alcohol levels correlating to blood alcohol content (BAC) levels via sweat secretion from the simple touch of a finger. Accurate test results appear within 6 seconds and can be texted to any pre-programmed phone number. If a driver's ethanol alcohol level exceeds the legal limit, the device will prevent the vehicle from starting.
